1) I'm just wondering, why do you really need such a strange-looking UI to
perform a quick search? Don't you think that a standard edit box will look
better? Certainly this would produce some problems with focusing but at
least there will be no overlapping UI fragments.
2) Don't think the title of File Structure dialog can be of any use. The
full path names are usually so long that you can't see anything.
3) The control layout of File Structure dialog is quite odd. The labels and
the checkbox seem to have no relative vertical alignment at all. The very
same issue exists in most of "generate xxx" dialogs.
